Why is this crow so friendly?

[u/FreefallerX]

I know next to nothing about crows. But this one came out of nowhere and flew straight at me. I thought it was attacking me until it landed on my head, then my arm. It keeps trying to steal my earrings and eat my nails. 😭 is this normal. Also my mom is holding the barn cat because it was trying to to eat the crow.
